  1. 11. Is it Just the Hormones? : Sex Steroids, Chronic Stress and Violence in Premenstrual Dysphoric Disorder

    Författare :Birgitta Segebladh; Inger Sundström-Poromaa; Marie Bixo; Kristina Gemzell-Danielsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; premenstrual dysphoric disorder; combined oral contraceptive; GnRH agonist; add-back; estradiol; progesterone; chronic stress; intimate partner violence; depression; anxiety; allopregnanolone; Obstetrics and gynaecology; Obstetrik och gynekologi; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Premenstrual depressive symptoms and mood swings affect 3-8% of women in fertile age. The female hormones are believed to be the cause. Progesterone is well studied, but estrogen is not, and either are other causes such as intimate partner violence and chronic stress. LÄS MER

  3. 12. Microalgal solutions in Nordic conditions : industries transition toward resource recovery?

    Författare :Lina Mattsson; Catherine Legrand; Elin Lindehoff; Hanna Farnelid; Kristian Spilling; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; algal cultivation; polyculture; resource recovery; seasonal variation; industrial partnership; CO2 mitigation; nitrogen removal; community composition; Ecology; Ekologi; Environmental Biotechnology; Miljöbioteknik; Miljövetenskap; Environmental Science; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Microalgal solutions can through photosynthesis recover greenhouse gas (CO2) and nutrients from industrial waste, reducing climate footprint and eutrophication. An added value to the process is algal biomass containing lipids, proteins, and carbohydrates with commercial potential for biofuel, feed, and fertilizer. LÄS MER

  4. 13. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

    Författare :Stina Lindqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

    Sammanfattning : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). LÄS MER

  5. 14. Consequences of rape : injuries, posttraumatic stress and neuroendocrinological changes

    Författare :Anna Tiihonen Möller; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Each year, approximately 3-4% of the Swedish female population experiences a sexual assault. Only a small percentage of these women will report the assault to the police, and even fewer will seek medical help. LÄS MER

  7. 15. Primary Marine Aerosol Production : Studies using bubble-bursting experiments

    Författare :Kim Hultin; Douglas Nilsson; Radovan Krejci; Ian Cousins; Åke Hagström; Erik Swietlicki; Stockholms universitet; []
    Nyckelord :sea spray; water temperature; dissolved oxygen; photosynthesis; bacterial emissions; V-TDMA; mixing state; eddy covariance; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosol particles affect the Earth’s climate, although their impact is associated with large uncertainties. Primary marine aerosol represents a significant fraction of the global aerosol budget considering the Earth’s 70-percentage coverage by oceans. LÄS MER
